The GeForce RTX 4090 is an absolute monster of a graphics card, but the battle for the next generation of GPUs is only getting started. On Thursday, AMD revealed its own 4K gaming champion, and the Radeon RX 7900 XTX and 7900 XT aim to topple Nvidia's goliath with help from a stash of smart tricks that could make David himself blush. In addition to improved ray tracing capabilities, the addition of AI cores, and memory galore, these first RDNA 3-architecture GPUs are also the first graphics cards featuring a multi-die "chiplet" design, swiping inspiration from AMD's epic Ryzen success. Just like when Ryzen disrupted Intel's stranglehold on CPUs, moving to chiplets helps AMD drastically undercut Nvidia's pricing. While the RTX 4090 costs a chest-clutching $1,599, and the impending GeForce RTX 4080 costs $1,199, the new 24GB Radeon RX 7900 XTX costs $999 and the 20GB RX 7900 will cost $899 when they launch on December 13.
